Switzerland-based MATCH is the main British provider for hospitality packages for the World Cup and is linked with UK sports event manager Byrom based in Cheadle, near Manchester.

Jaime Byrom, executive chairman of MATCH, and Mr Whelan's brother-in-law, said in a statement: "Notwithstanding our belief that the action taken against Mr Whelan was illegal and baseless, MATCH Services and I personally remain totally committed to assist the authorities from the 18th Precinct [police] or any other jurisdiction in FIFA's fight against illegal ticket sales."
